RSS Reader Plugin for only Titles (1 post)

I want to publish news from google/yahoo etc. but just the titles that I want to display in my sidebar. Is there any light weight plugin I can use on my site which won't require any building of tables in my database (or is that beneficial?). I checked out some javascripted rss readers, but I would like to have something on my own site. Any pointers will be most appreciated. Thanks!
